IMPROVEMENT lN PUSHlNG-BARS FOR RAILWAY-CARS.

Specification forming part of Letters Patent No. 200,136, dated February12, 1878; application filed January 4, 1878.

To all whom. it may concern:

Be it known that I, ISAAC S. GOLDMAN, of Edinburg, Christian county,State of Illinois, have invented a new and useful improvement forpushing and pulling cars on railways when the engine is on one track andthe cars to be pushed or hauled are on the other track, of which thefollowing is a specification:

The invention relates to pushing or switching bars for the use ofrailway-locomotives in backing cars off of side tracks while thelocomotive remains on the main track. Heretofore this work has usuallybeen done by means of a long heavy pole, which is taken up when used bytwo brakemen or other employs of the railway company, and one end of itplaced against the rear end of the tender, and the other end placedagainst the forward end of the car to be backed off. Then the locomotiveis reversed and put in motion, backing rapidly until the car is undergood headway, when the locomotive is suddenly stopped, allowing the poleto fall to the ground. This method is very objectionable: First, onaccount of the delay in finding and handling this pole, which is oftencovered by mud or snow, and which is a very disagreeable thing tohandle, and often causes long delays in getting the pole to work at all.Second, it is very objectionable on account of the danger in using it,for as the locomotive is backing rapidly it cannot be stopped at once,and as soon as it slacks in the least the pole falls, and is liable tobound under the wheels of the locomotive and throw it from the track.

The object of my invention is to provide a system of pushing andswitching cars that will do away with all unnecessary delays and dangersthat the present system involves.

Figure 1 of the drawings shows the pushing-bar and its attachments as itappears when attached to the tender of a locomotive and in the act ofpushing a car on the side track. Fig. 2 shows the pushing-bar andattachments when not in use and folded by the side of the tender.

The rod 0 is placed horizontally along the side of the tender of thelocomotive, and is secured to the sill of the tender by means ofeyebolts or hinges. To the forward end of the 'rod 0 is attached theforward end of the pushbar A by means of a very strong hinge-joint,welded firmly around the rod 0. The rear end of the rod 0 is providedwith a similar joint, to which is attached the jointed arm B. The outerend of the jointed arm B is attached to the rear end of the pushing-barA by means of a joint that is part of the casting G, which casting formsthe end band of the pushingbar A, and also the pulling-hook used inpulling cars forward. The jointed arm B is provided at the middle jointwith an extension inward from the joint of the outer section of the armB, which extension acts as a support to the arm when the arm isstraight. The horizontal rod 0 is provided at each end with a heavyrubber ball, E, through which it passes. Said rubber ball is situatedbetween the forward eyebolt or hinge and the forward hingejoint of thepushing-bar A. The ball E of the horizontal rod at the rear end issituated between the hinge-joint where the jointed arm is attached andthe rear eyebolt or hinge.

The object of the rubber balls E E is to act as a spring to receive thefirst pressure of the pushing-bar when it comes in contact with the carto be pushed or pulled.

When the ball E is compressed the end of the horizontal bar comes incontact with the casting F, which then receives the full pressure of thepushing-bar A.

The castings F F are securely fastened to the sill of the tender bymeans of bolts or otherwise. A lever, D,"is provided at the forward endof the horizontal rod 0, by means of which the pushing-bar is raised orlowered, at the pleasure of the operator.

Castings H H are secured to the sides of the tender-sill at each end ofthe horizontal rod, one being directly under the jointed arm B, theother under the forward end of the pushing-bar A, to act as a support tothe jointed arm B and the pushingbar A when the bar is lowered. I

What I claim is- 1. The combination of a pushing-bar, A, and jointed armB, end band and hook G, with a jointed arm, B, and end band and hook androd 0 with rubber balls E E, castings F G, substantially as described.13, lever D and castings H H, substantially as 2. The combination of apushing-bar, A, described. and jointed arm 13, and end band and hook GISAAC S.
